Fatigue was not cause the tragedy in Buffalo... it was pure incompetance, and lack of regard for SOPs, and situational awareness as it related to current weather conditions, and the effects of adverse weather on their aircraft. The bottom line is that the two of them were out to lunch. - captjns
Perhaps if you knew a bit more about fatigue you would see all of the above as symptoms of fatigue. How on earth can you have pilots commuting from one side/end of the country to the other without expecting this is beyond me. If there are more people out there in this same situation it is only a matter of time before it happens again. How many lives will be lost before the regulators wake up?
